Specific price by attribute : product cart calculation on add to cart?

[nbonniot]

Hello everyone,

 

I'm working on a Prestashop 1.4.8 in order to add the ability to choose an attribute when creating a specific price for a given product.

 

So far, it works great when I use the reduction way :

 

And the result on the product page :

 

 

But when I create a specific price with an "absolute" price (ie a price that should be taken in replacement of the attribute price) like this :

 

 

I got the following result : the price on the detail page is good, but when I click on "add to cart", I realized that the price displayed is the addition of the attribute price (defined at 100€) and the absolute specific price that I entered, with taxes (11,96) :

 

 

 

Could someone tell me where the cart price is calculated? Why in one case the good price is taken, and not in the other one?

 

I looked in Cart.php, CartController.php, AJAX cart module... I didn't find anything but the quantity update.

 

 

Many thanks for your return and suggestions,

 

Nicolas

hi,

I'm trying to add a function like this in my ps 1.4.8. I modified the function priceCalculation in the class product.php, and price calculation works well in all modules

Could you not try putting a minus sign in front of it?
